[Dune] Capability hasLevelIterator?

[Olaf Ippisch]

Hi Andreas,

in principle I agree with you that this solution would also be possible. 
However there is a danger in default implementations. They can be REALLY 
slow. And that would mean we would need to point the nose of the users to the 
point with which grid the implementation is not to be expected to be 
performant. If we don't do this, users might be frustrated. That's a reason 
why I would prefer to introduce a capability for features which are not 
mandatory, in this case the LevelIterator.

Regards,
Olaf
